The Outlander series is a commitment. You commit not only your time but your emotions and your expectations of future books. Diana Gabaldon is a master story teller and her books are best sellers and continually sold out for a reason; people cannot get enough. This follows the story of Claire and Jamie (and without revealing too much) and their journey and adventures through Scotland. You will genuinly fall in love with the characters and unlike most other books of this caliber, there are so many sequels you never have to leave them behind. And the sequels are just as well written, engaging and the best part: LONG!
The amount of research she puts into these books is enormous, I went and saw her speaking while she was in NZ and she is very intelligent and well spoken, which is reflected in the quality of her writing.
These books are amazing and I cannot recommend them highly enough.
